Impact of the central frequency of environment on non-Markovian dynamics in piezoelectric optomechanical devices

Abstract The piezoelectric optomechanical devices supply a promising experimental platform to realize the coherent and effective control and measurement of optical circuits working in Terahertz (THz) frequencies via superconducting electron devices typically working in Radio (MHz) frequencies.
